Description

Technical Field

[0001] The invention relates to the technical field of waste liquid filtration, in particular to an ultra-large flow intelligent liquid return automatic backwashing filtration station. Background Art

[0002] The backwash filter station is mainly used for the pre-low-pressure coarse filtration of the emulsion pump station or spray pump station at the coal mining face in the coal mine (it can also be used for the return liquid filtration of the emulsion pump station). Its function is to prevent dirt and impurities from entering the pump station and support systems, and further improve the service life of the hydraulic equipment.

[0003] Existing, such as China Patent No.: CN114904320B, an automatic backwashing return liquid filter station and its control method, the automatic backwashing return liquid filter station includes a frame and at least one group of filter systems arranged on the frame, and also includes a local monitoring system and a remote server; the filter system includes a filter, a backwashing control valve, a double stop valve, a unloading component, a drain valve and a pressure difference monitoring component. The pressure difference monitoring component of the invention transmits the monitored signal to the local monitoring system, and the local monitoring system sends the processed data to the remote server to realize remote monitoring, thereby improving safety; the present invention monitors the working state of the filter and controls the operation of the filter through the local monitoring system. When the pressure difference of the filter exceeds the set value or the backwashing time interval of the filter reaches the set value, the local monitoring system controls the filter system to backwash, thereby realizing the flexible switching of filtering and backwashing during the operation of the return liquid filter station, effectively ensuring the filtering efficiency of the filter and reducing the flow resistance.

[0004] Although the filter station in the above-mentioned patent realizes the flexible switching of filtration and backwashing during the operation of the return liquid filter station, effectively ensuring the filtration efficiency of the filter and reducing the flow resistance, the filtration mechanisms of the return liquid backwashing filter stations on the market are similar in the backwashing method, and both use liquid to flush the back of the filter surface to remove adhered impurities. This process has significant disadvantages. Backwashing requires a long shutdown and waiting time. During the shutdown period, the filtration supply of the return liquid containing impurities must continue. Once faced with the filtration task of ultra-large flow return liquid, the time-consuming shutdown in the backwashing stage will add a heavy burden to the entire operation process. From the perspective of filtration continuity, the shutdown waiting for backwashing causes interruptions in the filtration work, which not only affects the overall filtration efficiency, but also easily causes production stagnation and equipment pressure increase due to the accumulation and untimely treatment of return liquid, and even causes equipment failure due to frequent start-up and stop of various electrical components of the equipment. Therefore, the existing return liquid backwashing automatic station is difficult to cope with ultra-large flow return liquid filtration operations.

[0005] Therefore, we propose an ultra-large flow intelligent liquid return automatic backwashing filter station to solve the problems raised in the above background technology. Summary of the invention

The outer surface of the water injection pipe 304 is equidistantly fixed to the flushing pipe 305, the left end of the water injection pipe 304 is in a closed state and the right end is in an open state, the outer surface of the connecting shaft 203 is fixedly connected to the mounting block 206 near the swing rod 204, the outer surfaces of the opposite sides of the two mounting blocks 206 are located away from the connecting shaft 203 and are rotatably connected to the support wheel 207, and the outer surface of the support wheel 207 The surface and the outer surface of the extension nozzle 303 are tightly fitted, the mounting block 206 and the extension nozzle 303 are not fitted, the first motor 401 and the second motor 406 are both mounted on the left surface of the mounting plate 105 and the output ends extend to the right, the output end of the first motor 401 is fixedly connected to the first pulley 402, the right surface of the first pulley 402 is fixedly connected to the driving rotor 403, the driving rotor 403 and the magnetic rotor 302 cooperate, the output end of the second motor 406 is fixedly connected to the pinion 407, the outer surface of the pinion 407 is meshed with the large gear 408, the center of the right surface of the large gear 408 is fixedly connected to the left end of the connecting shaft 203, the large gear 408, the pinion 407 and the driving rotor 403 are all rotatably connected to the left surface of the casing 101,Multiple slide bars 501 are fixedly connected to the right surface of the housing 101, and a connecting plate 503 is slidably arranged between the outer surfaces of the multiple slide bars 501. The third motor 504 is fixedly installed on the right surface of the housing 101 and the output end extends forward. A spring 502 is sleeved on the outer surface of the slide bar 501 and the right end of the spring 502 conflicts with the left surface of the connecting plate 503. The output end of the third motor 504 is fixedly connected to a cam 505, and the outer surface of the cam 505 conflicts with the right surface of the connecting plate 503. The outer surface of the connecting plate 503 near the top is fixedly penetrated by a water inlet pipe 506, and the outer surface of the connecting plate 503 near the bottom is fixedly penetrated by a water outlet pipe 507. The water inlet pipe 506 and the water outlet pipe 507 are respectively arranged concentrically with the corresponding extension nozzle 303.

[0024] In this embodiment, when the device is used to filter the return liquid with a large flow rate, the return liquid is discharged into the housing 101 through the feed port 102. At this time, the impurities in the return liquid are retained outside the filter cartridge 301 below. At this time, the return liquid inside the filter cartridge 301 is in a filtered state. As the liquid level rises, the filtered return liquid will flow into the water injection pipe 304 through the flushing pipe 305, and finally be discharged through the connecting hole 109 and the outlet pipe 507. As the amount of impurities adhering to the surface of the filter cartridge 301 increases, the water outlet speed will be lower than the water inlet speed, so the liquid level will further rise. When the liquid level reaches the detection height of the liquid level sensor 104, the liquid level sensor 104 sends a signal to the external PLC controller to start the first motor 401 and the second motor 406. And the third motor 504 runs. When the third motor 504 runs, it drives the cam 505 to rotate. At this time, the return stroke of the cam 505 limits the maximum distance of the connecting plate 503 to the right. The spring 502 squeezes the connecting plate 503 to the right, thereby driving the water inlet pipe 506 and the water outlet pipe 507 to move to the right synchronously and separate from the filter cartridge 301. Then the second motor 406 drives the small gear 407 to rotate and drives the large gear 408 to rotate. At this time, the large gear 408 will drive the connecting shaft 203 and the swing rod 204 and the mounting block 206 on the surface of the connecting shaft 203 to rotate 180°. In this process, the symmetrically arranged swing rod 204 cooperates with the symmetrical guide groove 202 on the surface and the sliding groove 205 to push the filter cartridges 301 in the upper and lower positions to stagger front and back and complete the upper and lower position replacement. , then the third motor 504 drives the cam 505 to rotate, at this time the cam 505 pushes and squeezes the connecting plate 503 and cooperates with the spring 502, so that the water inlet pipe 506 and the water outlet pipe 507 are reinserted into the corresponding water injection pipe 304, and then the upper water inlet pipe 506 injects high-pressure liquid and flushes the high-pressure water close to the inner wall of the filter cartridge 301 through the upper water injection pipe 304 and the flushing pipe 305. During the process, the first motor 401 drives the driving rotor 403 to rotate slowly. Under the action of the magnetic field, the magnetic rotor 302 inside the filter cartridge 301 will drive the upper filter cartridge 301 to rotate synchronously, so that the flushing pipe 305 can fully flush the filter cartridge 301. This design makes it unnecessary for the filter cartridge 301 to stop and wait during the backwashing operation. It can undertake the task of continuous liquid return filtration, and its design is ingenious, which solves the problem that the existing backwashing filter station is difficult to cope with the ultra-large flow liquid return filtration operation. By installing a splash-proof shell 108 on the top of the casing 101, the liquid splashed out when the upper filter cartridge 301 is backwashed can be shielded and made to flow back into the casing 101. The bottom of the casing 101 is arc-shaped, so the filtered impurities will gather in the middle depression. The mounting plate 105 is mainly used to install the drive component 4. The opening above the casing 101 can also be used to inject the liquid to be filtered, thereby increasing the liquid inlet speed. The upper liquid injection can only be used for liquid return filtration with a low impurity content. The support wheel 207 is installed by setting the mounting block 206, which is mainly used to cooperate with the extension nozzle 303 to support the filter cartridge 301.To solve the problem that when the extension nozzle 303 on one side of the filter cartridge 301 is in the upper position, it is not at the intersection of the guide groove 202 and the sliding groove 205, resulting in loss of support and easy to fall and be damaged, the sliding rod 501 is mainly used to limit the movement of the connecting plate 503.

[0025] Embodiment 2: Figure 1-Figure 11 As shown, the right surface of the casing 101 is fixedly connected to a sewage pipe 103 extending obliquely upward near the bottom, and the inner wall brackets on both sides of the casing 101 are rotatably connected to the auger conveyor 107 near the bottom, and the auger conveyor 107 and the sewage pipe 103 correspond in position to each other. The outer surface of the first pulley 402 is connected to the transmission belt 404 for transmission, and the inner surface wall of the transmission belt 404 is connected to the second pulley 405 for transmission near the bottom. The second pulley 405 is rotatably connected to the left surface of the casing 101, and the second pulley 405 is fixedly connected to the left end of the auger conveyor 107 through the shaft.

[0026] In this embodiment, when the upper filter cartridge 301 is backwashing, the first motor 401 will synchronously drive the first pulley 402. At this time, the first pulley 402 will drive the second pulley 405 to rotate through the transmission belt 404. When the second pulley 405 rotates, it will synchronously drive the auger conveyor 107 inside the casing 101 to rotate, and then the impurities deposited at the lower part of the casing 101 will be discharged to the outside through the drain pipe 103, thereby reducing the amount of impurities inside the casing 101 and the filtering burden of the filter cartridge 301. The drain pipe 103 is in an upwardly tilted state. When impurities are transported into the drain pipe 103, due to the insufficient stroke of the auger conveyor 107, the impurities will not be discharged immediately, but will be gathered inside the drain pipe 103. As the impurities are continuously transported, they will gradually be squeezed out. In this process, when the impurities are squeezed, part of the internal water will be squeezed out and flow back to the inside of the casing 101, avoiding liquid loss and waste.

[0027] Embodiment 3: Fig.10 and Fig.11 As shown, a connecting hole 109 is provided on the right surface of the casing 101, the outer surface of the water outlet pipe 507 is in contact with the inner wall of the connecting hole 109, an inwardly contracted end 508 is provided at the left end of the water outlet pipe 507, a blocking plate 511 is provided at the center of the right side of the inwardly contracted end 508, a connecting piece 510 is fixedly connected to the right surface of the blocking plate 511, and the connecting piece 510 is fixedly connected between the inner walls of the connecting hole 109, an avoidance groove 509 is provided through the outer surface of the water outlet pipe 507 and the corresponding position of the connecting piece 510, a sealing sleeve 512 is provided on the outer surface of the water outlet pipe 507 and the corresponding position of the connecting piece 510, and the sealing sleeve 512 is fixedly connected to the right surface of the casing 101.

[0028] In this embodiment, when in use, the connecting plate 503 drives the water outlet pipe 507 to move to the right and then disengages from the water injection pipe 304 in the lower filter cartridge 301. During this process, the retracted end 508 of the water outlet pipe 507 will adhere to the blocking plate 511 on the inner side of the connecting hole 109 and form a closed state. Therefore, when the two filter cartridges 301 are replaced in position, the liquid inside the casing 101 will not enter the water outlet pipe 507 and cause misdischarge. Therefore, during this process, the external return liquid can be continuously injected into the casing 101 without stopping the injection. The design structure is simple and ingenious, which further improves the continuous filtering effect of the device. The avoidance groove 509 on the surface of the water outlet pipe 507 is mainly used to avoid the connecting piece 510 fixed on the inner wall of the connecting hole 109. During the avoidance process, the sealing sleeve 512 fixed on the surface of the casing 101 on the outside of the water outlet pipe 507 plays a role in sealing the avoidance groove 509 to prevent liquid leakage.

[0029] The effect and working principle achieved by the entire mechanism are as follows: when the device is used to filter the return liquid with a very large flow rate, the return liquid is discharged into the interior of the casing 101 through the feed port 102. At this time, the impurities in the return liquid are retained on the outer surface of the filter cartridge 301 below. At this time, the return liquid inside the filter cartridge 301 is in a filtered state. As the liquid level rises, the filtered return liquid will flow into the water injection pipe 304 through the flushing pipe 305, and finally be discharged through the connecting hole 109 and the outlet pipe 507. As the amount of impurities adhering to the surface of the filter cartridge 301 increases, the water outlet speed will be lower than the water inlet speed, so the liquid level will further rise. When the liquid level reaches the detection height of the liquid level sensor 104, the liquid level sensor 104 sends a signal to the external PLC controller. After sending the signal, the first motor 401, the second motor 406 and the third motor 504 are started to run. When the third motor 504 runs, it drives the cam 505 to rotate. At this time, the return stroke of the cam 505 limits the maximum distance of the connecting plate 503 to the right. The spring 502 squeezes the connecting plate 503 to the right, thereby driving the water inlet pipe 506 and the water outlet pipe 507 to move to the right synchronously and then separate from the filter cartridge 301. Then, the second motor 406 drives the small gear 407 to rotate and drives the large gear 408 to rotate. At this time, the large gear 408 will drive the connecting shaft 203 and the swing rod 204 and the mounting block 206 on the surface of the connecting shaft 203 to rotate 180°. In this process, the symmetrically arranged swing rod 204 cooperates with the symmetrical guide groove 202 on the surface to cooperate with the sliding groove 20 5 will push the filter cartridges 301 in the upper and lower positions to stagger forward and backward and complete the upper and lower position replacement, and then the third motor 504 drives the cam 505 to rotate. At this time, the cam 505 pushes the connecting plate 503 and cooperates with the spring 502 to make the water inlet pipe 506 and the water outlet pipe 507 reinsert into the corresponding water injection pipe 304. Then, the upper water inlet pipe 506 injects high-pressure liquid and flushes the position close to the inner wall of the filter cartridge 301 through the upper water injection pipe 304 and the flushing pipe 305. During the process, the first motor 401 drives the driving rotor 403 to rotate slowly. Under the action of the magnetic field, the magnetic rotor 302 inside the filter cartridge 301 drives the upper filter cartridge 301 to rotate synchronously, so that the flushing pipe 305 can fully flush the The filter cartridge 301 is designed so that the filter cartridge 301 does not need to stop and wait during the backwashing operation, and can undertake the continuous return liquid filtration task. The design is ingenious and solves the problem that the existing backwashing filtration station is difficult to cope with the ultra-large flow return liquid filtration operation. When the upper filter cartridge 301 is backwashing, the first motor 401 will synchronously drive the first pulley 402. At this time, the first pulley 402 will drive the second pulley 405 to rotate through the transmission belt 404. When the second pulley 405 rotates, it will synchronously drive the auger conveyor 107 inside the casing 101 to rotate, and then the impurities deposited at the bottom of the casing 101 will be discharged to the outside through the sewage pipe 103, thereby reducing the impurity mass inside the casing 101 and the filtration burden of the filter cartridge 301.When the connection plate 503 drives the water outlet pipe 507 to move rightward and separates from the water injection pipe 304 in the lower filter cartridge 301, during this process, the retracted end 508 of the water outlet pipe 507 will fit with the plugging plate 511 inside the connecting hole 109 to form a closed state. Therefore, during the process of the two filter cartridges 301 replacing each other, the liquid inside the housing 101 will not enter the water outlet pipe 507 and cause misdischarge. Therefore, during this process, the external return liquid can be continuously injected into the housing 101 without stopping the injection. This design structure is simple and ingenious, and further improves the continuous filtering effect of the device.

[0030] Among them, the liquid level sensor 104, the first motor 401, the second motor 406 and the third motor 504 are all prior art, and their components and operating principles are all public technologies, and no further explanation is given here. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
